APPARATUS FOR CARDING SAFETY PINS.

Application filed March 19, 1924. Serial No. 700,209.

This application is a partial continuation of my eopending case, SerialvNo. 551,972, liled April 12, 1922, and containsA subject matter takentherefrom. y

This invention relates especially to apparatus for carding safetyf pinsand similar articles by forming thercards with transverse or other slotsor apertures into which the closed or locked safety pins may be inlserted, particularly if the card is trans versely arched up when thepins are inserted in the slots. Then a breakable cardboard or otherretainer strip may be slipped along the bach ofthe card and maypreferably have bottom or edge projections so as to interlock ivitli theinserted pins anc securely' and positively retain them in position untilthey are removed for use and thereupon tear er break the retainer stripwhich is preferably adhesively secured to the card backv at a number ofplaces or positively retained in position as by interlockingprojections, tongues and apertures formed in the cooperating portions ofthe strip and card or pins. The card may be conveniently supported andforced into its transversely arched up position in a card holder havinginclined card grooves on each side, so that. when the card is forcedlongitudinally into the grooves or when the grooved edge portionsapgroach each otherthe card is arched up transverselyalong its centreline or where the transverse pin slots are formed therein. A dozen orother desired number of closed safety pins may be placed or fed into asuitable pintransfer block having slots to receive them and may behereby transferred and accurately placed in c00peration with theV pincard so that for instance their point portions enter and pass throughthe card slots sufficiently to allow the retainer strip tobe insertedfrom the same or lthe opposite direction as the card. T hen the pins maybe ejected fromA the transfer block by any suitable device and the cardreleased from the holder and discharged therefrom as by the insertion ofanother unfilled card into the holder.

In the accompanying drawing showing in a somewhat diagrammatic Way anillustrative embodiment of this invention Fig. 1 is a centrallongitudinal section through an illustrative carding apparatus;

l Fig. 2 is a transverse section showing the strip feeding and .gummingdevices;

Fig. 3 is a transverse section thereof taken substantially along theline 3--3 of Fig. l;

Fig. 4t is a rear view of the resulting Vpin card or package, and Fig. 5is a section thereof on line 5 5 of Fig. 4L.

The pins may be carded or packaged according to this invention Whileremaining in their closed o r locked condition in which they areregularly tumbled and polished and for this purpose the pin cardlt isformed with one or more series of pin slots such as 1G `which may betransversely arranged when a single roiv of pins is to be arranged onthe card. The pins preferably have their point meml'iersv insertedthrough these slots V(Si) which can be readily done by hand or other-Wise, especially if the pin card is transverse-v ly arched up vby anysuitable means; and when all of these safety pins, rings or othergenerally 'similar articles have been inserted into their slots, acardboard or other retainer strip or member l5 is inserted between; thecard back and the projecting portionsio'f the articles extending throughthe slots so, as to hold them in position during shipmentv around thereduced end 7 of the pin so asV to tend to separate the cardliolclersectioiis when the bushing 33 is screivedvin behind the spring.

more cams l0 pivoted about the pivotsV l1 in the endsof the pins 7 sothat when the ends 12 of these cams are swung upward into the positionindicated in Fig. 3 the card holder sectiensare closed against theaction of these4 springs 29 and the card 14 is'thereby forced up intothe definitely transversely arched up position indicated. The cardholder lis preferably formed with inclined These sections may, however,be closed by suitable devices such as one or card grooves i on eitherside of the same so that underthese conditions the card edges are forcel down alongv these inclined grooves to the c .rved bottoni j uortionsthereof, the arched up lower surface of the card holder recess jn'oinotinfY the desired posit-ion of the card adjacent l isc eove edgesrlhe safety pins or other generally similar articles may be inserted inany sanitableV way in these pin slots in the card which are preferablynot more than aboutha-lf as long'as the safety pins in order to moredefinitely hold them in position. For this purpose a pin transferlblock; such as 18V is K4desirable insupportingthe-series of pins andfacilita-t.n ing theirinsertionin the slots in the card. This transferblocwlg may be formed wien series of pinslotslwhich may extend com.-

rpletely through the block from top to bot-1-V tom, ifd'esired, and'be'spaced apart so as to correspond with the slots inthe cardl 14..

To retainthef pins in position inthe transfer-block any suitablefholdingdevices suchv asoneA or more pin supportingv plates 2O may loe-employedand mounted, if desired,

onthe pinsl projecting from each side of the transfer block 18 andVnormally forced inwardiinto the position indicated in F ig. 3bytheflight-splrings 21 so that the series of safetyV pins are thussupported by the inwardly projecting edges of Vt-hese plates.These-plates may, however, be released so as to simultaneously releasethe series of safety pins fromthe transfer block andfor this purpose theplate releasing cams 22 may be arranged on or adjacentV the upper faceof the transfer block so as tobe engagedby the edges 2d ofthe pinreleasing block 23 during the downward movement toward the transferblock so that it then wedges out-l ward these'releasing cams andtheconnected pin supporting plates 20. If desired also resilient or rigidejector members may be provided on this releasing block` and'one or,

more pin ejector-lugs 27 may be formed or yieldably mounted thereon soasto engage .the safety pins preferably after the supporting plates havebeenl substantially released andf thereupon positively eject Vthe safetypins from the transferblocl; by passing into the slots 28 in theblocl.The releasing bloclt may be supported and operated in any desired wayAas by the tubular carrier membersl 26 whichv may extend aroundv thecarrier rods secured to the die agonally opposite corners orportions ofthe transferblock, for example, these carrier elements being operatedmanually or mechanically in any desired way.

Y In using thisN apparatus to formfthepinl i packagel described the pincard lllmay be inserted intothe laterally openedgrooved card holderasb'ythe feedroller 50 which. engages the` lower v face ofjthe card"beneath nallydischarged from the holder,if desired. p

l/hen the card is longitudinally positioned inthe holder the holderVsections may be broughtV together as by the closing cams l0 so as totransversely arch up 'the card, which may thus be forcedup at itscentral portion somewhat above itstransverse guide ribs 3 formedin theupper surface of the card holder and the pin recesses 13 vtherein asshown in Figs: l' and. Then a series of safety pinsmay be brought intoproper engagement with the card as by the pin transfer block 18 so thatthe point or other portionl of each pin is preferably pushed throughtheV corresponding pin slot 1n the cardto ay sufficient extent'to leavean opening into which-the retainer `strip l5, having bottom or edgecorrugations such as to accommodate the pins and preferably havinggummed or otherwise adhesive upper surface or portions, 37 may beinserted as by the strip feeder l. vAs the retainer strip is" fedforward over the guider l5 by the feeder l or other means, the gummingroll LiO'is simultaneously rotated so as to apply any; suitable adhesivefrom the tank `a4: and supply roll t3 to the desired ypart, of theretainer strip. 'As shown in@` ig. 4l, the strip may have rounded.'yedge corrugations or locking projections. extending between adj acentpinsfto be thereby secured in position, and these edge projections maybe ladvantageously gummed as by Contact with the lateral projectingflanges orfconical portions 1-2 Vof the gumining roll 40, see Fig.y 2.rlhese gummed edge projections are of course strongly forced Aintoengagement with the card. back as soon as the card is released from theholder so that it can spring baci; into flatter position which forcesthe pins and interposed retainer Vstrip upward. Other separated orcontinuous gummed portions may be Vprovided instead of or in Vadditionto these gummed edge projections, and for this purpose the gumming rolll0 may have projections il at the proper intervals to apply theseparated spots 87 of gumto the back of thestrip l5, preferably betweeneach two adjacentpins.'Y The retainer strip is guidedva's by suitableguides d5, 48 so as to pass beneath;V the arched up card 16 and abovetheV pins projecting through the 4card Iil) as is seen in Fig. l, theone or more feeders l passing through suitable slots such as 49 in thegumming roll 40.

Thereupon the pins may be released from the transfer block as by thefurther descent of the releasing block 23 which releases and ejeets thepins from the transfer block and also, if desired, forces portions ofthe gummed or adhesive surface of the retainer strip into holdingengagement with the card back as by the downwardly projecting end orother portions suoli as 34, 35 of the releasing block which may forcethese card board elements tightly together. The trans` fer and releasingblock may then be withdrawn and the card of pins withdrawn from the cardholder preferably after the holder sections have been opened at least tosome extent to facilitate this withdrawal.

In some cases it is advantageous to employ interlocking projections ortongues and apertures formed in the cooperating portions of the retainerstrip and card. This method -may be employed alone or supplemental tothe adhesive method. As shown in Fig. 4, any desired number of apertures38 may be formed in these parts as by severing them along the crossed orperpendicular dotted lines 37 by means of one or more sharp edgedpiercing members, and then forcing back against the adjacent rear faceof the retainer strip, for instance, the interlocking tongues orprojections 39 which are thus formed. There this is done by a stampingor die operation under heavy pressure, the adhesive which has preferablybeen applied between these parts, tends to become quickly set as in boxstaying operations and materially helps to hold the parts together insuch positions as are shown in Figs. 4 and 5. If desired, however, anumber of apertures such as 38 may be pierced in these cooperatingmembers of heavy paper or light cardboard so yas to force the tongues 89through tiis aperture after which they may `be advantageously forced orcrushed down against the baclr of the retainer strip, for example, toprevent accidental longitudinal displacenient of the retainer strip.

rl"l1is invention has been described in connection with .a number ofembodiments, forms, proportions, parts, arrangements, materials, methodsof connection, operation and use, to the details of which disclosure theinvention is not of course to be limited, since what is claimed as newand what is desired to be secured by Letters Patent is set forth in theappendedl claims.
